Excavations at Kanie (Mazovia Voivodeship) in Poland have uncovered the second largest centre of iron production in this area, dating back 2000 years.

Finds that were of greatest interest to the archaeologists were a timber well of unusual design, a number of bloomery furnaces for smelting iron and according to the researchers, the site fits well into the pattern of other known ironworks settlements located in the Blonie Plains.
